    Abstract: A method of determining a color value of a target object is provided. The method includes capturing an image having a color calibration object and a color reference object. Computed calibration color values for the color calibration object and a first computed reference color value for the color reference object may be determined based on the single first image. A color calibration coefficient may be determined. A corrected reference color value may be determined based on the color calibration coefficient and the first computed reference color value. A second image may be captured. A second computed reference color value of the color reference object and a computed object color value of the target object may be determined based on the second image. A corrected object color value may be determined based on the corrected reference color value, the second computed reference color value, and the computed object color value.
